cristallo glass
Quick Summary
Cristallo was a type of clear, colorless glass developed in Venice by the 15th century. It was made with soda and was highly workable, allowing for intricate designs. Venetian glassmakers guarded their techniques, including those for cristallo, with severe penalties for defectors. This led to the spread of Venetian glassmaking styles, known as façon de Venise, across Europe. While cristallo often had a brownish or grayish cast, its clarity and resemblance to rock crystal made it highly prized. Venetian glass was exported widely, and its influence shaped glassware production throughout Europe for centuries.123
